have problems to erase a flash section. I'm using MK22FN512VLH12.
i'm using the C90TFS Driver. The erase command is set correct in the FCCOB-registers and the flash machine responses no errors. But the flash section isn't erased. It's untouched.
The flash command sequence is copied to ram and is performed.It's the same disassembly like the "FlashCommandSequence" - function
If i put a wrong section address in the FCCOB-register it responses with an ACCERR.
The code seems to work if i erase/write section in the other block ( address > 0x3FFFF).
I can't share the code.
